Specification of Letters Patent.

Patented Mar. 23, 1915.

' Application filed November 19, 1915. SeriaI No. 8Q1,775.

To all whom it may concern Be it known that I, HARRY W. CRANE, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and

State of Pennsyly anim have invented a newand useful Improvement in Windows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to windows, and particularly'to that class in which counterbalanced sashes, in addition to having a vertical movement in a window frame, are capable of swinging on a horizontal axis midway between their upper and lower ends. Such a Window is set forth in the patent to George, No. 7 76,177, dated November 29, 1904.

The object of my invention is toprovide a construction of window capable of being constructed in its entirety, except the glass pane, of metal.

'In the drawings, which show a preferred embodiment of my invention: Figure l is a perspective of Window frame, shoe and sash,

all partly broken away, with the sash partly swung open. Fig. 2 is a perspective of the frame and shoe with the sash and certain parts of the pivotal connection removed. ig. 3 is a vertical section through the sash and shoe in a plane parallel'to the glass. Fig. 4 is a'face view of the shoe. Figs. 5, 6 and 7 are sections respectively on the lines 5-5, 6-6 and 77 of Fig. 3. Fig. 8 is an enlarged view showing a detail of my construction. I

The shoe a is one of a pair of shoes adapted to slide in vertically-extending grooves or'runners in the window frame and between hich is/pivotally supported the sash b on a ihorizontal axis midway between the upper and lower ends-.of. the shoes. Each shoe is made from a hollow piece of metal. This hollow metal bar is of'uniform Width throughout measuring from the outside to the inside thereof, but is of varying and irregular depth measuring from the window frame toward the sash.

In its central portion (see Figs. (iv-and 7) the shoe is of substantially rectangular contour and of comparatively small depth. In. one end portion, say the uppergend' portion (see Fig. 5) the shoe is of medium width except near its inside and outside faces. Ad oining one face (say its inside face) it 1s of. comparativly small depth, or of substantially the depth of its central portion, while near its other or outside face it has its maximum depth. In'the other end portion, say the lower end portion, the shoe is of med um depth except near its inside and outside faces. Adjoining one face (say its outside face) it is of comparatively small depth, .or of substantially the depth of its, central portion, while near its other or inside face it has its-maximum depth. In other words, the shoe is of maximum depth on'i ts,outside face at one end and on its inside face at its other end and is of-minimum depth on its inside face at the first named end and on its outside face at the last named end, while its central portion, being of minimum width, is virtually recessedrelatively to the end portions, which are, as above stated, of medium width except in the portions thereof adjoining the inner and outer faces. The changes in depth are abrupt, the metal being stepped, or bent substantially at right angles to the direction of extension of the'shoe, to effect the variation in depth described. The sash is also a hollow metal structure and is of uniform width throughout, measuring from the outside to the inside thereof. The body thereof, except along its outer and inner faces, is of uniform depth. In one end portion, say the upper end portion, the sash, near one face, say its inner face, is of maximum depth, while near its other or outer face it is of minimum depth. In the other end portion, say its lower end portion, the sash, near one face, say its outer face, is'of maximum depth, while near its other or inner face, it is of minimum depth. In other words, the sash is of maximum depth on its outer face at one end and on its inside face at the other 1 end and is of minimum depth on its inside face at the first named end and on its outside face at the last named end.

T he central'portion of the sash is of maximum depth along only its outer and inner faces, thus forming an inclosed longitudinally-extending space between the shoe and sash. Itwill thus be observed that each of the gtwo members, In its end portions, is ofa three-stepped contour on the face thereof opposed to the face of the other, thus forming hollow {projections on aneinher ,conforming to insets on the other meifnber; while in the central portions, the. shoe and sash abut against each other adjoining their front and rear faces, but a rectangular inclosed space is formed between them, which space extends. above and below the central pivot. The exact fitting ofthe two memhers is effected by making. the hollow projections exactly correspond in dimensions with the insets 'with which they engage.

By reason of the foregoing construction,

the sash may be swung on its pivot in :one

' direction without interference between sash a an annular flange on the shoe, an axial bolt,-

receiving orifice and also an annular space adapted to the reception of a filler ring a. A collar d, providing a bearing for the bolt, extends within said bolt-receiving orifice, and has a flange extending into the hollow interior of the sash and underlying the wall thereof opposite the shoe. The bolt 6 extends through the collar 03, the head of. the bolt being within the hollow" interior of the sashand engaging the flange of the collar d. The other end of the bolt extends into the hollow interior of the shoe and has threaded thereon a pair of nuts f. A cup-shaped spring washer g is sleeved on the bolt within the hollow interior .of the shoe and is confined between the nuts f and-the wall of the shoe opposite to the sash.. The wall of the shoe opposite the sash 'is offset, both above and below the bolt e, to form vertically ex tending shallow depressions or pockets h. In the space between the sash and shoe, and

above and below the bolt 6, is a flanged holdmg plate thawing ridges j adapted to the depressions h; Springs In, confined between the sash and the holding plate '5, hold the plate a tightly against the shoe, and'the ridges 7' within the depressions h, when the sash is closed. j v

By the above construction, the sash is preyented from turnin' from its closed position unless a degreeo force is exerted sufficient to force the holding plate i'out of its pocketed engagement with the shoe and against the tension of the springs k. In turning the sash, the holding plate 41 overrides the non-pocketed faces of the offset part of the shoe and frictionally resists turnling, whereby the sash is held open at any angle to which it may be turned on its axis. ii/hen the sash is turned to its closing position, or in parallelism with'the shoe, the

License ri jnre brought apposite the depressions the sash by means of a strip 1- extending across the angle between the sash and pane and confining between it and the sash and pane a piece 8 of felt or similar compressible materia lr To further insure full closure of the window a spring detent is provided near the end-of the closing members. '1? his detent consists of a depression t in one of the windows', shown as'in the sash, and a spring projection inthe other member, in this case the shoe, which may either be in the form of a flat spring a, as shown in Figs. 3 and 5, or of a spring pressed roller a) as shown in l ig. 8.

Having now fully described my invention, what ll claim and desire to protect by Letters Patent is:

1. In a window, in combination, a shoe which throughout a part of its length has a three-stepped contour on the face thereof opposite the sash, forming a projecting rib ad oining one face and a corresponding inset adjoining the other face, a sash which throughout a part of its length'has a similar times-stepped contour on the face thereof adjoining the sash, forming a projecting rib opposite and" corresponding to the inset in the shoe and an inset opposite and corresponding to the rib in the shoe, said shoe-in another part of its length being of less depth than in the body of its stepped portion, said sash in the corresponding part of its length having, adjoining its inside and outside faces, projecting ribs closing the space between shoe and sash, and a pivot pin connecting the shoe and sash.

2.1na window, in combination, a shoe, each end portion of. which isofa threestepped contour on-the face thereof opposite the sash, forming in one-end portion a projecting rib adjoining the inside face and a corresponding inset adjoining the outside face, and in the other end ortion a similar rib adjoining the outside ace and'a corresponding inset adjoining the inside face, a sash of a similar three-stepped contour in its two end portions, the ribs of one member being arranged respectively opposite the insets of the other member, one member in its central portion. presenting a fiat face and the other member in its central portion having, adjoin-in the inside and outside face, projecting ribs closing the space between shoe its length has a three-stepp' and sash, and means pivotally connectin the sash and shoe at their central portions,

3. In a window, in combination, two members, one a shoe which throu bout a part of contour on the face thereof opposite the sash, forming a projecting-rib adjoining one face and a corresponding inset adjoining the other face, and the other a sash which throughout a part of its length has a similar three-stepped contour on the face thereof adjoining the shoe, forming a projecting ribopposite and v corresponding to the inset in the shoe and an inset opposite and corresponding to the rib in the shoe, one of said members at another part of its length having a flat face while the other member in the correspondin part of its length has, adjoining its insi e and outside faces, projecting ribs inclosing a space between shoe and sash, and a pivot pm connecting the shoe and sash.

4. In a widow, in combination, two memhere, one a shoe which throughout a part of its length has a three-stepped contour on the face thereof opposite the sash, forming aprojecting rib adjoining one face and a I corresponding mset adjoining the other face, and the other a sash which throughout a part of its length has a similar threestepped contour on the face thereof adoining the shoe, forming a projecting rib opposite and corresponding to the inset in the shoe and an inset opposite and corre-' sponding to the rib in the shoe, one of said members at another part of its length having projectin ribs adjoining both its inside and outside] aces, while the other member 'has a'face spaced from the face between the ribs of the "first member, thereby forming aninclosed space between shoe and sash, and a pivot pin connectin sash and extending into sai .inclosed s ace.

In testimony of which invention, I ave hereunto set my hand, at Philadelphia, on this 28th day of October, 1913.
